The fates of Sebastian and his therapist Martin, as well as radio producer Olivia, best friend Lucy, and husband Francis, are improbably yet inextricably linked in a novel about extinction and survival, inheritance and loss.

It's the summer of 2021, and Sebastian is in treatment following a breakdown that has left him grappling with his fragile grip on reality and his persistent hunger to connect with the biological mother who abandoned him as a child. His therapist, Martin, is facing challenges of his own, including his adopted daughter's tenuous relationship with her own biological mother--a predicament that makes Sebastian's struggle feel uncannily proximate to her own. Olivia is producing a radio series on catastrophic natural disasters, which itself seems to be running parallel to the events unfolding in her personal life, as her best friend Lucy faces a grave diagnosis, and her husband, Francis, pursues his mission of re-wilding the world. Over the course of the next year their fates collide in outrageous and poignant ways, as each of their destinies is revealed in a marvelous new light.
